Sometimes I cannot connect anymore to my Mi Band 3 with Bluetooth.
If I then turn off Bluetooth on the S10, I cannot switch it on anymore. I have to reboot the phone to get Bluetooth back.
I've noticed the Fitbit app regularly complains about last sync. I open the app and its reconnecting to my Fitbit band.
I assumed it was an Android 10 /Fitbit app compatibility thing that Fitbit would have to update.
Maybe I'll send Samsung feedback in case it is a bluetooth issue.
It might be due to compatibility of the app and new Android, but still make sure to share an error report with us via Beta Feedback option in Samsung Members app!
If it can be fixed on our side, then it will help us out for sure
